The history of the development of the universe Physics homework is coming soon Thank you

The theories of the origin of the universe are the Gaitian Theory, the Armillary Heaven Theory, the Xuanye Theory, the Geocentric Theory, the Heliocentric Theory, the Nebula Theory, and the Great ** Theory.

1, Gai Tian said.

The earliest theory of the structure of the universe in ancient China believed that the sky was round, like an open umbrella; The earth was square, like a chessboard, and the sun, moon and stars passed through the sky as if they were climbing.

2, Hun Tian said.

The theory of armillary heaven is a cosmological theory of the ancient Han people. According to the Hun Tian theory, the relationship between heaven and earth is like the relationship between egg white and yolk in eggs, and the earth is wrapped in heaven.

3. Xuan Ye said.

Xuanya theory believes that the universe is infinite, that the universe is full of gas, and that all celestial bodies float and move in the gas. The laws of motion of the stars, the sun and the moon are determined by their respective characteristics.

4. Geocentrism.

The geocentric theory, also known as the Tiandong theory. Geocentrism is a theory that the earth is the center of the universe and is stationary, while all other planets orbit the earth. It is also the doctrine of the faith of the ancient Church.

5. Heliocentrism.

The heliocentric theory, also known as the geokinetic theory, was proposed by Copernicus. It is the antithetical theory of the movement of celestial bodies, which holds that the sun is the center of the universe, not the earth.

6, Nebula said.

Nebula theory is a general term for various hypotheses about the origin of the solar system from primitive nebulae. The initial cosmic space was filled with extremely low-density interstellar gas and dust material, which gradually gathered into many large galactic clouds under the gravitational attraction, and then gave birth to a large number of stars in the galactic clouds to form galaxies.

7, big ** said.

The big ** theory originated from a discovery that shocked the world. The conclusion of this discovery is that the universe is expanding at a high rate, and all extragalactic galaxies are moving away from us. Based on this, astronomers thought that since the universe is expanding, it is possible that there will be a starting point for expansion.

First of all, the universe is a unity of space, time, matter, and energy, and it is not an exaggeration to describe it with all good adjectives. Buddhism believes that nothing is eternal, in the same way, the universe is finite and not infinite, everything has its own reincarnation, a cycle, the universe is a cycle from the beginning to the end, this round has a beginning and an end, so its time and space are limited. Since the origin of human civilization, we have been pursuing the mystery of the universe, ancient Chinese astronomy has a wealth of ideas about the structure of the universe, the Western Zhou Dynasty has the "Gaitian Theory", that is, "the sky is round like a cover, the place is like a chess game".

Similarly, the ancient Egyptians believed that the earth was floating on water, and the ancient Greeks believed that there were pillars under the earth. And the most special thing is the Brahma that is circulated in India, everything in the world is a dream, when he wakes up, everything is gone, and after he falls asleep again, the world starts from the beginning, which is the wonder of reincarnation. With the progress of civilization and the development of science and technology, our understanding of the universe has slowly entered the right track, at least partially confirmed, in the second century AD, Ptolemy proposed a complete geocentric theory, and in 1543, Copernicus proposed a scientific heliocentric theory.

In 1609, Kepler developed the heliocentric theory, and Galileo Galilei used a telescope to confirm its correctness from a factual point of view.

The universe is a general term for the vast expanse of space and the various celestial bodies that exist in it, as well as the diffuse matter. The origin of the universe is an extremely complex issue. The universe is the material world, which is in constant motion and development.

For thousands of years, scientists have been searching for when and how the universe came to be. To this day, many scientists believe that the universe was formed by a big ** that occurred about 13.7 billion years ago. The matter and energy in the universe are gathered together, and condensed into a very small volume, the temperature is extremely high, the density is extremely high, and the huge pressure is generated in an instant, and then a large ** occurs, and the reaction principle of the big ** is called quantum physics by physicists.

The big ** caused the matter to be scattered, the cosmic space continued to expand, and the temperature also dropped accordingly, and then appeared in all galaxies, stars, planets and even life in the universe one after another. The wormhole eruption theory believes that the universe we live in now originated from the opening of a space-time gate.

In many parallel universes, there is an extremely ordinary parallel universe, in this universe, the largest black hole continues to devour other celestial bodies in the universe, its mass continues to increase, so large that its gravitational force can destroy all material forms, first its core into an energy body, energy gradually accumulates, and finally breaks through its shell, releases energy outward, forms a wormhole, and the door of time and space opens. When the energy is fully released, the wormhole stops erupting and the space-time gate closes. The high-energy particles that ejected have evolved over a long period of time to form the universe we live in now. The erupting wormhole becomes an ordinary celestial body in the previous parallel universe, which is why we can't find the center of the universe.
